Please did FY have that role 1970 - 75?
I was in Met. throughout that period and we had little visibility of such activities, probably because just about all Met. for the V. Force originated in HQSTC and we had little or no involvement.
We certainly saw/ heard Vulcans from time to time of course. "The sound of freedom" as I told my whingeing neighbours in Bessacarr, Doncaster.
